The Study And Application On Key Techniques Of Web Resources Management Based On RDF

Resources is the object of privilege management and access control. Resources management is the basis of privilege management and access control. With the rapid development and wide application of the Web, Web Resources has become the most important network resources. More and more information system use Web techniques to exploitation. At the same time, Web information system need Resources management. Accordingly, Web resources management is of great practical values.Aiming at the Web characteristics of semi-structured, dynamic, diversity and disorder, this dissertation studies several key techniques, including the Web resources description, the organization and structure analysis of the Web resources, Web robot, the resources extraction and update.The main work of this dissertation is as follows:1. Systemic researched on relative problems and technique status quo.On the basis of researched on Web architecture and main techniques, discussed the Web resources conception and Web resources conception management, analyzed several key techniques on the Web resources management.2. Put forward a resource description method in the face of privilege management. This method was implemented by RDF and meet the needs of sime- structure represent-ion, resource automatic manage and privilege management.3. Detailedly researched on the organization and structure of the Web,and introduced the construction arithmetic of logic structure resources tree.This arithmetic can construct logic structure resource tree,which can express the relation between resources, convenience for resources management.4. Designed automatical collection arithmetics and introduced the extraction process. These arithmetics and extraction process has the merits of high automatization and none manual work, improving the management efficiency.5. Implemented a Web resources management system based on RDF.This system has satisfied with privilege management demand, possessing the function of Web resources description, automatical collection and resources tree build and so on.
